Introduction
Introduction
The Section describes how to operate the meter via an optical
interface.
• It also explains the detail information of all interface command sets
of Standard Commands for Programmable Instruments (SCPI) used
in the meter.
• The remote control operation enables the user either to manually
operate the meter via a terminal or to execute a host computer
program automatically.

Chapter 1 Remote Interface Overview
The following figure shows the USB type optical cable connecting for
the meter and a host computer communication.
The computer is added a virtual RS-232 COM port when the user
plugs the USB type cable and installs the USB driver.
• The remote interface is a serial binary data interchange, which
operates from 2400 to 19200 baud rate.
• The communication port of the 7016 is designed in full duplex,
which makes the meter more reliable and efficient in data taking.

Chapter 2 Setting Remote Interface Parameters
In order to operate the meter via a host computer or terminal, the
parameters in interface within the 7016 have to match the parameters
in the serial interface provided by the host or terminal.
The following procedures will guide the user to set up interface
parameters within the 7016 to comply interface with the host.
The default settings of the meter at factory are 9600-baud rate, non-
parity, 8 data bits, and 1 stop bit (9600, n, 8, 1).
The following table indicates the factory settings and user selectable
communication parameters by using remote interface.
Echo
With ECHO ON, the meter echoes (returns) all the characters
whatever it receives.
Print-Only
• The remote indicator of the 7016 is flashing when the meter is set to
Print-Only ON.
• If the remote interface of the 7016 is under Print-Only mode, the
7016 will print out the measured data when the measurement cycle
is completed.
• The 7016 auto-sends the newest data to a host continuously.
• The 7016 doesn't accept any commands under Print-Only mode.
Setup Procedures for Communication Parameter
To ensure the remote interface will operate appropriately, user may
need to configure the remote interface parameters on Setup Mode.
Please refer to operation procedures of POWER-ON OPTION.

Chapter 3 Commands Summary
Overview of Command Type and Format
• All commands must be entered in the upper case.
• There are two types of the 7016 programming commands: IEEE
488 common commands and Standard Commands for
Programmable Instruments (SCPI).
• Some commands are device-specific to the 7016. They are not
included in the version 1999.0 of the SCPI standard. However,
these commands are designed with the SCPI format in mind and
they follow the syntax rules of the standard.
Common Command Format
• The IEEE 488 standard defines the common commands as
commands that perform functions like reset and system query.
• Common commands usually come with the asterisk "*" character,
and may include parameters. Some examples of Common
command like: *IDN?, *RST, *CLS, GTL, LLO.
SCPI Command Format and Query Format
• The SCPI commands control instrument functions.
• A subsystem command has a hierarchical structure that usually
consists of a top-level (or root) keyword, one or more lower level
keywords, and parameters.
• The following example shows a command and its associated query:
Commands
Summary Chapter 3
A. CONFigure:VOLTage:DC 0.5: Set the primary display to the
DC voltage measurement , and
select the 500mV range.
B. CONFigure? : Return the function of the primary
display measurement.
• CONFigure is a root level keyword with the second level
keyword, VOLTage, and 0.5 is the command parameter.
• The query command ends with a question mark "?".
SCPI stems from IEEE488.1 and IEEE 488.2. Although the IEEE
488.2 standard addressed some instrument measurements, it
principally dealt with common commands and syntax or data formats.
Please refer to the IEEE488.2 and SCPI reference manual for more
information.

Terminator
A terminator is a character sent by a host, which identifies the end of a
command string. A valid terminator consists of two-byte data:
<CR> (Carriage Return, ASC(&H0D))
<LF> (Line Feed, ASC(&H0A))

Chapter 4 Responding Message
Return result
• After the meter executes a query command the return of the result
will be in the following format:
• If communication of the meter is under print-only mode, the meter
will print out the measured data when the measurement cycle is
completed. The printed data are only for primary display.
The format of printed data will be shown as following:
• On the meter warning the return of the prompt will be in the following
format except Xon and Xoff:
Data Types
• Returned message is the ASC II string from the meter responding to
a query.
• A query is a command followed by a question mark.
The following table is explanation for data types.
